GENEVA (AP) ― The ugly side of the beautiful game emerged Thursday as the U.N.’s top human rights official joined soccer officials and players in calling for an end to the “crime” of racism in sport.

U.N. High Commissioner for Human Rights Navi Pillay said racist insults and chants, Nazi salutes, petitions against players and denial of hiring based on color or ethnicity have no place in sports.

“Sport, at its best, is inclusive, generous-hearted, and fundamentally multicultural, based on values such as teamwork, loyalty, merit and self-control,” Pillay told a forum at the U.N.’s European headquarters.

“There must be accountability for racist offenses,” she said. “It is a crime and must be treated as such by sports authorities.”

AC Milan player Kevin-Prince Boateng, former France captain Patrick Viera and several FIFA and European soccer officials attended the event. Several officials said they were taking action through a FIFA anti-racism task force.

Boateng recalled how he felt “angry and offended” when he kicked the ball into the stands and led teammates off the field to protest being abused by fans of Italian fourth-tier team Pro Patria during an exhibition match in January. He credited the backing of his teammates with sparking broader international outrage.

“Racism can be found on the streets, at work and even in football stadiums. There were times in my life when I didn’t want to deal with this subject. I tried to ignore racism, similar to a headache that you know will go away if you just wait long enough,” he said. “But that was (a) misconception. Racism does not go away. If we don’t confront it, it will spread.”

Vieira said racist abuse is common in stadiums.
